Pointers? What do you think this is, C? ;-) Try this:
def spam_averse_email_address( email_address, text ):
"""return HTML-embedded javascript to create a spam-averse mailto link"""
def char_codes( a_string ):
return ",".join(str(ord(a_char)) for a_char in a_string)
return """<script type="text/javascript">
<!--
document.write(
'<a href="mailto:'
+ String.fromCharCode(%s)
+ '">'
+ String.fromCharCode(%s)
+ '<\/A>');
// -->
</script>""" % (char_codes(email_address), char_codes(text))
The newlines within the triple quoted string are important; use that
function something like this:
print "<html>"
print "<head><title>Title</title></head>
print "<body>
print "<P>%s</P>" % spam_averse_email_address( '[EMAIL PROTECTED]',
'click here to email me' )
print "</body>"
print "</html>"
You mentioned accessibility; make sure that your HTML does something
sensible if the user's browser doesn't do javascript.
